The Payment Card Industry Data Security Standard (PCI DSS) is the global security baseline for organizations that store, process, or transmit cardholder data. Compliance is contractual (card brand rules) and assessed through Self-Assessment Questionnaires (SAQs) for smaller scopes or full audits for Level 1 merchants and service providers.
Scope is the hidden cost driver. Every system that touches PAN, or can affect the security of systems that touch PAN, falls into assessment. Tokenization and hosted fields exist largely to shrink that boundary. A merchant that never sees PAN can qualify for SAQ-A; one that vaults PAN in application databases inherits SAQ-D complexity.
Using a PCI Level 1 token service provider does not automatically transfer all obligations. Merchants remain responsible for how they integrate, log, and access token APIs, and for any PAN they still retain. Due diligence on subprocessors, key management, and incident notification is part of every enterprise procurement.
Veliro is built to PCI DSS Level 1 with Secure Fields keeping PAN off merchant servers. Network tokens reduce PAN retention; where PAN fallback is required, it stays inside Veliro’s vault boundary. Your integration choices determine your SAQ path, design for the narrowest scope that still meets portability goals.
Annual PCI cycles should revisit whether new features reintroduced PAN into your environment, marketing iframes, support tools, and data exports are frequent scope creep vectors that undo earlier SAQ wins.
